Layer Details
Removable, washable top cover
A cover that unzips for washing, treated with Bugshield cover technology and OEKO-TEX 100-certified. That makes it easy to keep fresh.
Memory foam protector
A memory foam layer that allows the top cover to move freely while the first memory foam layer works independently. That means the cover and foam can each do their own job.
Premium-grade aurora foam
A high-density foam with an open cell structure for breathability and moisture evaporation. Its wave technology feels slightly firmer at the foot end, so you get zoned support as well as airflow.
Supporting foam layer
A second layer of high-grade supporting foam that adds depth and density for structure and stability. It also cushions pressure points.
2,000 pocket springs
The first layer of 2,000 springs in the 5,000 composite spring unit, which compresses first to support your contact points. That means the springs respond where you press down most.
1,000 nano springs
A layer of 1,000 super-soft nano springs that gives extra bounce. That means a bouncier feel underneath the foam.
2,000 more pocket springs
A further 2,000 pocket springs that complete the composite spring unit. They give the layers above a springy base to work from.
The support base
A high-density, environmentally responsible foam base that gives solidity to the layers above. It keeps the whole build stable.
Non-slip base
A base layer that keeps the mattress in place on the bed base. That means less chance of it shifting around.

Key benefits
- A single's width each: At 90cm per person, each of you gets the width of a UK single, which means a restless partner's movements are far less likely to reach your side.
- 15cm more each than a king: Compared with the UK king, the UK super king gives 15cm more each, which you'll notice most if one of you sleeps spread out.
- Room for night-time visitors: When a child or the dog joins you, the 6ft x 6ft 6in surface means everyone still gets a share rather than someone clinging to the edge.
- King length, extra width: The UK super king is the same 200cm length as the UK king, so taller sleepers keep that length and gain 30cm of width on top.
This size suits you if...
You share the bed every night with a partner who tosses and turns, or children and a large dog regularly end up in with you, and your bedroom is big enough that a UK king would look a little lost in it.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m. We'd recommend the UK king instead, which gives 75cm each and needs at least 2.7m x 2.9m.

FAQ's
Is the Brook + Wilde Suprema UK super king big enough for two adults and a child?
For a child who wanders in, yes. The 180cm width gives 90cm each to two adults, so a small child in the middle usually still leaves both of you room. If it happens most nights, the UK super king is the size we'd choose, because the UK king gives 75cm each before anyone else arrives.
What room size do I need for a UK super king Suprema?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable once bedside tables go on both sides. In a loft conversion, the slope often decides which wall the bed takes, so check you have full head height along the whole 200cm length.
Will a Brook + Wilde Suprema super king fit up my stairs?
Measure your stairwell, landing turns and bedroom door swing before ordering. At 180cm wide and 29cm deep, the UK super king is a large item to manoeuvre, and older houses with tight turns can be a squeeze. Check the brand's own delivery guidance on how it arrives before you buy.
What size duvet and sheets fit a Suprema super king?
A 260 x 220cm duvet suits the UK super king, with super king fitted sheets. The Suprema is 29cm deep, so check the fitted sheet pocket depth before buying. Bedding at this size costs more than king sets, which is easy to forget when budgeting.
Is a UK super king worth it over a king for a restless partner?
If disturbance is the main problem, extra width tends to help more than changing feel. The UK super king gives 15cm more each than the UK king, which puts real distance between you. Yes, it needs a bigger room, but if you have the space it's the more reliable fix.
